MACHINE FOR FINISHlNG HEELS OR OTHER PARTS OF BOOTS OR Sl-lOESl SPECIFICATION forming part of Letters Fatent No. 743,988, dated November 10, 1903. Application filed February l2, 1901iV Serial No. 46.995` (No model.)

resident of Lynn, county of Essex, Commonwealth of Massachusetts, have invented cers tain Improvements in Machines for Finishing Heels or other Parts of Boots or Shoes, of

which the following description, read in connection with the accompanying drawings, is

a specification.

The invention relates particularly to machines for applying Wax to the edges of heels of boots and shoes and rubbing the waxed heel to produce a finished surface thereon.

The present invention is especially useful when applied to machines in the use of which carnauba-wax is employed in finishing the heel. This Wax, either pure or in preparations containing it in a large proportion, isl

preferable for use in finishing leather surfaces, because it gives a permanent bright polish and does not mold. Surfaces which are nished bythe use of compounds of other lWares are likely to mold-that is, they are likely to turn a grayish color-and as leather surfaces finished with. carnauba-Wax retain their bright polish and do not mold this Wax is generally preferred for suchwork. It has been found preferable to melt carnauba-Wax before using it and to apply it in liquid form to the Work member of the machine. Itis characteristic of carnauba-Wax, howeveglhat it solidies very quickly, becoming lumpy and unfit for use in finishing a leather surface, and in using it vdiiculty has been eX- periencedlin delivering it to the work memloer in proper condition for application to the work. To overcome this diiculty, I have devised mechanism for insuring the delivery of the Wax to the work member in melted condition. To this end l have employed, in coinbination with the Work member and with Wax-supplying means, a conveyor for transferring the wax to the Work member and means for heating the conveyer, whereby the melted and hot wax is delivered directly to the part .which is in engagement with the Work. y It will, however, he understood that While theppresent invention is especially usevention is of course not limited to such use,

and many of its features maybe employed to advantage on machines in the use of which other kinds of Wax are employed.

Fig. 3 is a vertical section through the machine-column. Fig. 4 is a detail on the vertical section-line 4 4, Fig. 2. Fig. 5 is a plan View showing the wax-holder and Wax-conveyor and connections. Fig. 6 is a plan of parts shown in Fig. 5 with a plurality of wax-conveyors. Fig. 7 is a detail showing the spring for holding the wax-holder in elevated position. Fig. 8 is an elevation, on an enlarged scale, showing the Wax-spreader and connections. Fig. 9 is a section on line 9 of Fig. S.

On the shaft 2 is a loose pulley 4, to which the driving power is applied by belt from any suitable source. Said pulley has a frictionfaced part 6 for engaging a similar part 10 on pulley 22, Vand connected therewith is ashipper device with handle 8, whereby in order to start or stop the machine said pulley 4 is moved endwise on shaft 2, it being thus engaged with or released from pulley 22. A belt 20, passing round the pulley 22, idlers 24 26, and pulley 2S, operates for rotating the shaft 30. On the top end oli-shaft 30 is a spiral gear 32 in mesh with a similar gear 34 on the horizontal shaft 36,'which shaft 36 isjournaled for movement rotatively in the part a, of the head 3S, and it carries the Work member 40. A second shaft 42 has support for movement rotatively in the arm 44, which arm in turn is supported on the head 38. The shaft 42 carries on its outer end a tool 46, such as is commonly in use for beading the boot or shoe heel seat, and in ciose proximity on said shaft are the cloth-covered polishingtool 48 and the brush 50. Pivotallyconnected with the machine-head are hoods 52 54, located above the members 48 50, respectively. Said shaft 42 also carries a pulley 56, which is connected by a belt 58 with pulley 60 on shaft 36, whereby motion is imparted frein IOO which screw has threaded engagement with the machine-column and may be actuated for lifting and lowering the machine-head to different altitudes. The shaft 30 has spline-andkey engagement with pulley 28 in order that the shaft-actuating mechanism shall automatically adjust itself to any change in the altitude of the head. The head 38 also is permitted rotative movement in the machinecolumn, whereby to shift the positions in a horizontal plane of the mechanisms supported thereon, and when suitably stationed the head may be securely clamped in the machine-co1- umn by operating the screws 66 68, to which end the column is cutlongitudinally on line 70.'

The work member 40 may be of any suitable construction, but preferably is of the type shown and described in detail in United States Letters Patent. to Beaudry, No. 616,432, dated December 20, 1898. The work meutber as shown herein is heated by gas conducted from a suitable supply through the pipe 74, and the plate 76 is set in position for resting the tread-surface of a boot or shoe heel While it is being treated by the work member. In a bracket 80 on the machine-head 38 is the shaft 82. On said shaft is a worm-gear 84 in mesh with a worm 86 on the shaft 36. Said shaft 82 carries in the top end the eccentric-pin 88, which enters the groove 90 in a plate 92 on a shaft 94, and this combination reciprocates the shaft 94 endwise. The shaft 94 carries a part 98, which is loose thereon and embraces by a strap 99 a nut 100, which nut has screw -threaded engagement with shaft 94 and may be turned for shifting the position of part 98 on shaft 94 longitudinally. A carrier 102 is connected pivotally with part 98 by means of the pin 104, on which the carrierhasa free rocking movement. Said movement is limited by the walls 106 108 on said carrier bringing up againstthe part 98. (See Fig. 9.) On the outer free end of carrier 102 is a brush 110, which is detachably connected with the carrier by a screw 112. Said brush rests upon the face of the work member 40, being depressed theretoward by the Weight of carrier 102, and obviously it is moved across said face by the endwise movement of shaft 94. The carrier 102 is mounted to turn on pivot 104, and the convexed surface of the member 40 acts as a fulcrum beneath the brush 110, so that when the brush is moved across said face the line of weight or pressure of the carrier 104 on said brush passing from one side to the other side of the highest part of said face will cause the brush to rock over the said highest part of said face and contact with the part or section of the face of the work member which is disposed on the side toward which the brush is rocked. This combination opcrates for distributing and spreading wax on the face of the work member and will automatically adapt itself to the various shapes and sizes of different Work members.

Supported to turn on the bracket 80 is a handled part 120, which carries a rod 122 in .ceives the lower portion of a conveyer 132,

which consists of a metallic Wheel fast to a shaft having a rigid portion 135 and a exible portion 136. The rigid .portion 135 of the shaft is mounted in a bearing 137 in a cast.- ing 150, (see Fig. 5,) and the flexible part is connected to the lower end of the positivelydriven shaft 82, above described. Said connection is made by a sleeve 140, which carries a spring-actuated plunger 142 in position to enter a socket 144 in said shaft, whereby is secured a grip sufficient to turn the conveyer under normal conditions, but adapted to slip in case movement of the conveyer is resisted abnormally-for example, by the unmelted wax in said holder. To prevent the sleeve 140 from becoming detached from the shaft 82, a groove is cut in shaft 82, which terminates in the socket 144, so that the plunger 142 when it is lifted from the socket 144 will travel in said groove. The conveyer is preferably heated, and a gas-pipe 134 is shown for this purpose. The wax-holding guideway is so located with relation to the trough-like compartment iu which the conveyer rotates that the wax slides by gravity down the guideway against-the side of the conveyer-wheel 132. The heat for the conveyer may be so regulated that the wax is melted as fast as it is needed, and the melted wax flows down into the trough 133, which is so narrow that it is nearly filled by the conveyer-wheel. The wheel keeps the liquid wax in the trough hot and as it rotates in the direction ofthe arrow thereon delivers the hot wax to the work member 40. As shown in the drawings, the conveyer' is so located with relation to the work member ICO IIO

that the wax is delivered to the work member from the portion of the conveyer-wheel which is just above the top of the trough 133. The arrangement of the parts is such that only a small quantity of Wax is kept melted, and the narrow trough which holds the liquid Wax and the conveyer are so located with relation to the work member that the melted wax is kept hot and is but little exposed to the air in being delivered to the work member.

The casting 150, in which the shaft of the conveyer is journaled, is an arm pivotally mounted on a sleeve 153 of a collar 154, fastened on a rod 152, which is projected from the frame of the machine, -(see Figs. 5 and 7,) and the collar 154 has an arm or projection in which is mounted an adjusting-screw 156.

IZO

The screw 156 engages the lower side of the arm or casting 150 and adjustably supports the outer end of said arm and the conveyer 132, carried thereby. By operating the adjusting-screw the conveyer may be positioned nearer to or farther from the work member for the purpose of causing the conveyer to deliver more .or less wax to the said member. It is also obvious that the screw 156 may be employed to move the conveyor into and out of operative position. Vhen in its operative position, the conveyer 132 is not required to be in touch with the face of the work member; but when it is approximately close to said face the wax is taken from said conveyor, it being seemingly sucked 0E by the heated rapidly-moving Work member, and thereafter the wax is spread over said face by the brush 110. The amount of wax taken may be regulated by the distance between the conveyer and the face of the work member, as above stated. Another way of regulating the quantity of wax taken is by varying the temperature of the conveyer, as when very hot it will carry a thinner film of wax, and consequently deliver less to the work member than when it is less heated, and still another way is to vary the speed of its movement. In Fig. 6 two conveyers are repre sented, which may be employed whenever it is desirable to deposit the wax on dierent circumferential surface lines of the face of v the work member, and obviously a greater which is adapted to engage in a notch 20S,

extending obliquely int-o the hub 201. The spring 202 therefore serves to detaehably secure the hub 201 of the arm 200 on the sleeve 153 and also acts on the arm 200 to tend to raise the end thereof which carries the waxholderA 130. The arm 200 is stopped in Aits uppermost position by contact withthe bearing of shaft 135. The spring 202 thus'constitutes yielding means for sustaining the wax-holder in operative relation to the conveyer. The'arm 200 and the wax-holder may be removed in order to substitute another holder containing a dierent kind or quality offwax. When a wax-holder which has before been used and in which the trough 133 normally occupied by the conveyer is filled with unmelted Wax is jput iu place, the unmelted wax in the trough is pressed against the conveyer by the spring 202. The spring supports the wax-holder, with the unmelted wax pressed against the conveyer, until during the operation of-the machine the heated.4 conveyer melts the wax in the trough. When the wax becomes melted, the spring forces the holder up into its normal position, Whereit is stopped by contact with the bearing of the conveyer-shaft. v l

In use the Work member 40 is preferably heated to a higher temperature than the waxconveyer 132. This renders the semiviscous Wax ou the conveyer 132 susceptible to the drawing influence of the rapidly moving member 40, and it also causes the wax to become heated to a very highdegreeou the face of the member 40 preparatory to deposit on the surface of the work. The wax-treated surface as it comes from member L10 is somewhatrough, and it is next applied to the cloth-covered tool 4S, which'smooths over the outer face of the wax film. The heel is next applied to the beading-tool and finally to the polishing-brush 50. It is found desirable for the workmen, having once taken the boot or shoe in hand, to apply it to all of these tools before putting it down. This makes it im portant to assemble all said work members or tools in such positions that they Will'be accessible tothe workmen without traveling. The shafts 36 and 42 therefore are terminated at unequal distances from the axis of thermaohine-head, and the work member 40 is stationed on the end of shaft 36. This allows the shafts to be set close together, so that a Workman standing in position of work relation to shaft 42 may withoutwalking reach forwardly to the work member 40.

The work member 40, it will be understood, is designed for finishing the surfaces of boot and shoe heels and has its working face convexed cross-sectionally in substantial coun` terpart of the concave cross-sectional line of the heel to be finished. It is of course obvious that a work member shaped for treating other surfaces than boot and shoe heels could be substituted for the work member 40.
